How do I switch between 12-hour and military time / 24-hour time?

To switch between 12-hour and 24-hour time: 

  1. Head to the Home (🏠) or Calendar (📅) tab 
  2. Tap the cog / settings icon (⚙️) in the top right corner 
  3. In the 'Preferences' section, look for '24 hour time'. If it's on, you'll see time in a 00:00 format. If it's off, time will show in an AM/PM format.
